Abstract
This research primarily evaluated the efficacy of multiple different magnetic resonance imaging (MRI) sequences for monitoring of bone healing after tibial plateau leveling osteotomy (TPLO) in dogs. Titanium surgical implants were utilized intra-op in order to minimize expected susceptibility artifacts during imaging. T2-weighted DIXON, T1-weighted Turbo Spin Echo (TSE), and dynamic contrast-enhanced (DCE) sequences were used to quantify sclerosis, bone remodeling and hyperintensity and vascular perfusion at the osteotomy site 4 weeks after surgery. There was no significant correlation between MRI grades and radiographic grade of healing at 10 weeks post-operative. MRI is a feasible imaging modality for evaluation of the canine stifle after TPLO.
